sqlite_lib.bash

Bash library to use SQLite in bash scripts

Dependencies:

• sqlite3

Tested with sqlite 3.13.0 in ArchLinux

Usage:

Import the library into your script

source sqlite_lib.bash

Call sqlite_create_fetch_array with two parameters: the first is the sqlite db file, the second is the sqlite query (must be in quotes).

sqlite_create_fetch_array db.sqlite "SELECT id, Name, Surname FROM Customers"

The function sets two variables:

1. num_rows contains the number of rows of the query result
2. rows (bidimensional array) contains the data. The first index is the row result index, the second is the Column name of the result data

for (( i = 0; i < num_rows; i++ )); do
  echo ${rows[$i,"id"]} ${rows[$i,"Name"]} ${rows[$i,"Surname"]} 
done

Full example:

#!/bin/bash
source sqlite_lib.bash
sqlite_create_fetch_array db.sqlite "SELECT id, Name, Surname FROM Customers"
for (( i = 0; i < num_rows; i++ )); do
  echo ${rows[$i,"id"]} ${rows[$i,"Name"]} ${rows[$i,"Surname"]} 
done
